Some nutrients and antioxidants may improve skin and hair health, but more research is needed to confirm these benefits.

This article explores how various nutrients and metabolic processes impact wool and hair follicle function in animals but reports no new experimental findings.

In this study, researchers found that most food supplement labels in Portugal recommend daily mineral doses exceeding the EU's Recommended Daily Allowance, with some even surpassing the Tolerable Upper Intake Level, raising safety concerns regarding potential adverse effects.

This study highlights the role of innate immunity and purinergic signaling in regulating hematopoiesis and hematopoietic stem/progenitor cell specification. The researchers observed that these ancient pathways operate both paracrinally and autocrinally within HSPCs, maintaining their developmental function throughout evolution.

This review examines physical methods like electron paramagnetic resonance spectroscopy, Raman spectroscopy, and differential scanning calorimetry, highlighting their complementary capabilities in analyzing biomolecular structures and mycobacterial interactions with reactive oxygen species and antioxidants.

The researchers reported that epitestosterone treatment reduced eicosanoid levels generated by cyclooxygenases and lipoxygenases in rabbit liver samples with carrageenan-induced inflammation.

In this study, researchers reported that wound dressings made from bacterial cellulose composites modified with soybean protein (BC/7S and BC/11S) improved wound healing and reduced scarring in rat models, with BC/11S showing superior outcomes.

This review examines the molecular effects of photobiomodulation therapy, particularly its influence on gene and protein expression related to inflammation and cell functions, but reports no new clinical results.

This study reports that different animal species exhibit distinct hair scale patterns and elemental compositions, which can aid forensic investigations in identifying animal hair.

This study observed that selenium retention in rat hair and nails was influenced by the chemical form of dietary selenium and methionine status, suggesting caution when using these tissues to assess selenium status.

This research underscores the critical role of the human microbiome in health, highlighting potential therapeutic benefits of interventions like fecal microbiota transplantation and probiotics for conditions linked to microbiome dysbiosis, such as metabolic disorders and inflammatory diseases.

This report describes a patient with biotinidase deficiency presenting bilateral optic atrophy, and confirms autosomal recessive inheritance through enzyme dosage analysis in the patient and family members.

This study found that sensitive scalp is characterized by increased pH levels, redness, altered sebum composition, and a disrupted microbiome, suggesting these features could inform treatment approaches.

This study found that sodium and potassium hair levels may serve as sex-specific indicators, with slight differences in copper and iron content between males and females, particularly during the female reproductive period.

In this review paper, the authors explored the composition and role of lipids in human hair, highlighting their importance for hair texture, moisture retention, and tensile strength, while noting that the understanding of hair lipids' functions remains controversial and requires further research.

This publication presents a library of precision geometric medicines that reportedly kill harmful bacteria and fungi while sparing beneficial organisms, using a delivery system that targets pathogens specifically and avoids ecological harm.

In this study, GC/MS analysis revealed variability in the quality of Syrian herbal formulations for BPH, with variations in tocopherol content, presence of parabens, and shortages of certain phytosterols.

This study found that early biochemical screening and molecular confirmation are crucial for distinguishing profound from partial biotinidase deficiency, which supports timely treatment and management in symptomatic children.

This study found that moose hair can effectively monitor previous mineral states for most elements, except zinc, and mineral uptake differs between male and female moose.

This study identified several DPC-specific proteins, including ITGB1, IGFBP3, and THBS1, as potential biomarkers for hair growth modulation through proteomic and network analysis.

The demineralized bone matrix scaffold is better for cell attachment than the mineralized bone allograft.

This study investigated various proteins as eco-friendly hair perming agents for Asian hair and found that bovine serum albumin and keratin achieved perming results comparable to commercial products, while also increasing hair moisture, indicating a protective effect during heat styling.
